Abstract
A breathing mask comprises: a frame; a forehead support frame connected to the frame pivotally to allow the forehead support frame to shift toward or away from the forehead of a patient; and an adjusting member connected to the frame rotatably and having an adjusting slope. The forehead support frame has a joining part in contact with the adjusting slope so that the forehead support frame is driven to rotate pivotally through the rotation of the adjusting member. Through the matching between the adjusting slope and the joining part, the breathing mask converts the rotation of the adjusting member to the shifting of the forehead support frame; and through rotating the adjusting member, the height of the forehead support frame relative to the forehead of the patient can be adjusted. In use, the forehead support frame can be shifted by rotating the adjusting member with a single hand.
